UNITED STATES PATENT OFFICE.

EDWARD E. REIGLE, OF BALTIMORE, MARYLAND, ASSIGNOR OF ONE-THIRD T0 JOHNZAJIC, OF BALTIMORE, MARYLAND.

METHOD OF WELDING COPPER.

No Drawing.

Patented June 2, 1914.

To all whom it may concern Be it known that I, EDWARD E. RmeLE, acitizen of the United States of America, residing at Baltimore, State ofMaryland, have invented certain new and useful Improvements in Methodsof Welding Copper, of which the following is a specification.

This invention relates to a method of welding metals.

The object of the invention is more particularly to provide a method ofwelding copper.

An efficient method of welding copper has long been sought but so far asI am aware, no practicable method is now known for accomplishing thisobject.

In carrying out the invention I take the metal to be welded and boil itin a strong solution of chlorate of potash for about two hours. Asbefore stated, I then find that the copper may be cold welded withoutany trouble and the resultant union of the metal will be complete.

While I have found that boiling the metal in chlorate of potash, for thetime stated,

efficiently accomplishes the desired object, it is possible thatsubjecting the metal to the action of chlorate of potash in the presenceof heat would secure the desired result, and I Wish it to be understoodthat the present invention contemplates such procedure and that it isnot limited to the precise method outlined.

Having described my invention, What I claim is:

1. The herein described method, which consists of boiling the copper tobe welded in a solution of chlorate of potash and then Welding the same.

2. The herein described method which consists of boiling the copper tobe Welded for two hours in a solution of chlorate of potash and thenwelding the same.

In testimony whereof I affix my signature in presence of two witnesses.

EDWARD E. REIGLE.
